the common species in various particulars, and especially in the disposi- 

 tion and number of its teeth. These in the iudividual examined were 

 only thirty-six in number, whereas in the Sus Scrofa they are forty-four ; 

 in the Sm Papuenshs they may, however, amount to forty, as it seemed 

 probable, from the appearances observed behind the last molar of each 

 jaw, that the rudiments of a sixth molar were contained within the bone. 

 The tusks, as noticed in the specific character, are not longer than the 

 other teeth, and their sockets, although higher, are not directed out- 

 wards. The absence of these formidable organs, some resemblance in 

 form, and the shortness of the tail, indicate, according to MM. Lesson 

 and Garnot, the passage from the genus Sus to the Peccaries. But there 

 is no organ analogous to the dorsal gland of the latter animals, nor is 

 there any unpleasant odour ; each foot also possesses four hoofs. Its 

 length is three feet, and its height nineteen or twenty inches. It is very 

 common in the forests of New Guinea, and furnishes an agreeable ali- 

 ment. 



Numerous Cetacea were observed during the voyage, and remarks on 

 these form the subject of the fourth chapter. Many of them were pro- 

 cured for examination, and among these were several species of Delphi- 

 nus altogether new to science, and others hitherto imperfectly understood. 

 Near the Falkland Islands was obtained the Delphinus hivittatus, a new 

 species with the upper parts of a deep shining black, and the under parts 

 white, aad marked along each side by a broad satiny white stripe, which 

 is interrupted, and becomes broader, opposite to the dorsal fin. In se- 

 veral parts of the South Seas occurred the species described by Lacep^de 

 and Desmarest as the Delph. Peronii, the Delph. leucoramphus of the 

 able naturalist whose name is con)memorated in its trivial appellation. 

 Owing to the absence of the dorsal fin, this animal is necessarily referable 

 to the genus Delphinapterus. It is nearly six feet long, and has thirty- 

 nine teeth on each side of either jaw. The Delph. albigena of MM. 

 Quoy and Gaimard, suspected by these authours (o be a variety of their 

 Delph. cruciger, was also observed in the same seas, and proves, accord- 

 ing to MM. Lesson and Garnot, to be a distinct species, to which they 

 give the name of Delph. siiperciliosus. In the Bay of La Concepcion, 

 on the coast of Chili, exists in great numbers another new species, Delph.
